Purify our conscience, Almighty God, by your daily visitation, that your son Jesus Christ, at his coming, may find in us a mansion prepared for himself; who lives and reigns with you, in the unity of the Holy Spirit, one God, now and forever. Amen.

The First Lesson: Isaiah 7:10-16

Again the Lord spoke to Ahaz, saying, Ask a sign of the Lord you God; let it be deep as Sheol or high as heaven. But Ahaz said, I will not ask, and I will not put the Lord to the test. Then Isaiah said: “Hear then, O house of David! Is it too little for you to weary mortals, that you weary my God also? Therefore the Lord himself will give you a sign. Look, the young woman is with child and shall bear a son, and shall name him Immanuel. He shall eat curds and honey by the time he knows how to refuse the evil and choose the good. For before the child knows how to refuse the evil and choose the good, the land before whose two kings you are in dread will be deserted.”

The Psalm: Psalm 80:3-7

3 Restore us, O God of hosts: *

Show the light of your countenance, and we shall be saved.

4 O Lord God of hosts, * how long will you be angered

Despite the prayers of your people?

5 You have fed them with the bread of tears; *

You have given them bowls of tears to drink.

6 You have made us the derision of our neighbors, *

And our enemies laugh us to scorn.

7 Restore to us, O God of hosts; *

Show the light of your countenance, and we shall be saved.

The Second Lesson: Romans 1:1-7

Paul, a servant of Jesus Christ, called to be an apostle, set apart for the gospel of God, which he promised beforehand through his prophets in the holy scriptures, the gospel concerning his Son, who was descended from David according to the flesh and was declared to be Son of God with power according to the spirit of holiness by resurrection from the dead, Jesus Christ our Lord, through whom we have received grace and apostleship to bring about the obedience of faith among all the Gentiles for the sake of his name; including yourselves who are called to belong to Jesus Christ, to all God’s beloved in Rome, who are called to be saints: Grace to you and peace from God our Father and the Lord Jesus Christ.

The Gospel: Matthew 1:18-25

Now the birth of Jesus the Messiah took place in this way. When his mother Mary had been engaged to Joseph, but before they lived together, she was found to be with child from the Holy Spirit. Her husband, Joseph, being a righteous man and unwilling to expose her to public disgrace, planned to dismiss her quietly. But just when he had resolved to do this, an angel of the Lord appeared to him in a dream and said, “Joseph, son of David, do not be afraid to take Mary as your wife, for the child conceived in her is from the Holy Spirit. She will bear a son, and you are to name him Jesus, for he will save his people from their sins.” All this took place to fulfill what had been spoken by the Lord through the prophet:

“Look, the virgin shall conceive and bear a son,

And they shall name him Emmanuel,”

Which means, “God is with us.”

When Joseph awoke from sleep, he did as the angel of the Lord commanded him; he took her as his wife, but had no marital relations with her until she had borne a son; and he named him Jesus.
